Q6030LH5

Triacs Overview

The Littelfuse Q6030LH5TP is a bidirectional triac belonging to the ALTNSTR ISO series, designed for high-reliability AC power control applications. It features a 600V rated repetitive off-state voltage and supports a continuous RMS on-state current of 30A. The device utilizes a TO-220-2 package for through-hole mounting. Key electrical parameters include a maximum gate trigger current of 50mA and an on-state voltage of 1.4V. The component exhibits a low off-state leakage current of 10µA at VDRM and operates within a temperature range suitable for industrial environments.

Triacs Feature Summary

• ALTNSTR ISO technology provides enhanced robustness against dV/dt transients and improved thermal stability compared to standard triacs.
• Integrated isolation design facilitates safe operation in applications requiring galvanic separation between control and load circuits.
• High surge current capability ensures reliable performance during startup conditions and inductive load switching.

Triacs Applications

• Solid-state relays (SSRs) for industrial automation
• AC motor speed control systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'TP' when ordering, as it denotes tape-and-reel packaging which differs from the tube packaging often associated with the base model number. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to finalizing procurement specifications.

Triacs Selection Notes

Select this component for designs requiring 30A continuous current handling with 600V blocking capability. Ensure the heat sinking strategy accommodates the thermal resistance of the TO-220-2 package under full load conditions. Verify that the gate drive circuit can supply the required 50mA trigger current reliably across the specified operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Qxx30xHx series of high-power triacs. The series is characterized by its use of ALTNSTR ISO technology, which distinguishes it from conventional thyristor structures by offering superior immunity to false triggering and better performance in harsh electrical environments.

Triacs Replacement Considerations

Direct substitutes may include other 30A/600V ALTNSTR ISO triacs from Littelfuse such as the Q6030LHS3, provided pinout compatibility and thermal characteristics are verified. Cross-brand replacements require careful evaluation of gate sensitivity and holding current parameters.
